Opencv-python: Version 4.3.0.38 does not ship with libGL.so

[Domibor]

Expected behaviour

Updating from 4.3.0.36 to 4.3.0.38 should miss system libraries.

Actual behaviour

import cv2 breaks.

(opencv) root@619f7f2a9b63:/tmp/body# python -c "import cv2"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/opt/conda/envs/opencv/lib/python3.6/site-packages/cv2/__init__.py", line 5, in <module>
    from .cv2 import *
ImportError: libGL.so.1: cannot open shared object file: No such file or directory
(opencv) root@619f7f2a9b63:/tmp/body# 

Steps to reproduce

Using a fresh python environment inside this container docker run -ti continuumio/miniconda3:4.7.12 /bin/bash:

conda create --name opencv python=3.6 pip=20 --yes
conda activate opencv

It works with previous release

Issue submission checklist

• [x] This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
  

• [x] I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
  



• [ ] The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")


• [x] I'm using the latest version of opencv-python

See: https://github.com/skvark/opencv-python/issues/370#issuecomment-671202529

libGL.so is whitelisted by auditwheel. It will not be shipped with the wheels.

I tried to modify the docker file and made some changes in requirements and still couldn't know how to deploy without this error in GCP and locally it is working good. Please let me know if there are any solutions to it. Thanks.

@Yamini-DS I believe you either should depend on opencv-python-headless instead of opencv-python (if your code is the only place where you have a dependency on opencv-python), or ensure that after all python packages installation steps you install opencv-python-headless (to rewrite the package - a hacky option), or install the required GUI stack to the docker image (probably, will take several hundreds of megabytes)
